Answer:
117
Step-by-step explanation:
f(x) = 21x + 12
f(5) = 21(5) + 12
f(5) = 105 + 12
f(5) = 117
The answer choice which explains whether the function is a direct variation or not is; This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
<h3>Which explains whether or not the function represents a direct variation?</h3>
It follows from the task content that the function passes through the origin and hence, if the function was represents as a linear function, it's y-intercept would be zero.
Furthermore, the slope, otherwise termed it's rate of chage is constant and is evaluated as; $5 per hour. Hence, the aforementioned form the basis for the classification of the function as a direct variation.

If I'm not wrong, you must draw a graph for this
y=-2x +2
sub x=-1 ,0 and 1
and do the same for y=x^2-3x
and plot the coordinates
don't worry y=-2x+2 will be a straight line because it's x is to the power of one
and **to find the no. of solutions, refer to ur graph and count the number of point of intersections and that will be ur answer
Hope this helps :)
